I just went through and enabled "Facebook Connect" feature which allows you to link you G6P account with Facebook.
You might have connected the Facebook Connect icon at the top of the screen when you go to log in. To enable it, you must first login with your G6P name and password. Then you click on "Connect" and type in your Facebook info, and it will then connect the two. You can now log in directly by just logging in with your Facebook account.
New users will also benefit as it will import their "real name" and birthday and such into their G6P profiles, should they chose to.
You also may notice a "Like" button on the top of some threads on the forum, such as this one. You can "Like" these and they will show up that you liked them on Facebook. Note however that only topics you can view when you aren't logged in are "Likeable." If it is a topic you must be logged in to read then the "Like" button will not show up.

Profit?
